G Scale Trains are usually referred to as Garden Trains since they are the largest of the model trains and are used outdoors as well as indoors.
A scale model is most generally a physical representation of an object, which maintains accurate relationships between all important aspects of the model, although absolute values of the original properties need not be preserved.ther model scales are generally given as a ratio that expresses what a measurement on the model represents on the actual object. When buying a model train, scale sizes are referred to by letter name, not number ratio. 00 gauge is a hybrid of two measurement systems.
